To a/ZZ whom, it may oon/cern,.-

Be it known that I, ENOS P. OURREY, a citizen ofthe United States, residing at Woodward, in the county of Woodward, Oklahoma Territory, have invented a new and useful Plow, of which the following is a specification.

This invention relates to plows; and it has for itsobject to provide a device of this class in which the component parts shall be capable ofl desired adjustment with relation to each other, in which the lay or share shall be capable of being reversed, so that either side may be exposed to wear, thus increasing the life of this part, and in which that part of the landside which is mostexposed to wear may i be readily detached and replaced as occasion 4 is a longitudinal sectional view taken on the line worin Fig. 1. Fig. 5 is a perspective detail view showing the plow-pointdetached. Fig. 6 is a transverse sectional View taken on the line y y in Fig. 1. Fig. 7 is a plan View of the share or lay detached. Fig. 8 is a plan view showing the wear-plate detached.` Fig.

9 is a plan View showing the adjusting-plate detached. Fig.v 10 is a detail view showing av portion of the front end of the landside with the supporting-plate attached thereto. Figs. .7, 8, 9, and 10 have been shown enlarged.

Corresponding parts in the several gures are indicated by like characters of reference. 1 designates the point of my improved plow, from the upper edgeof the sideof which adjoining the 4land a. wing or flange 2 extends laterally, as shown.` That portion of the point which adj oins the land is provided near its rear end with a shoulder 3, from which a bracket v 4 extends in a rearward direction, as shown.

lTo the opposite sides of this bracket are secured plates 5 and 6, the outer one ofwhich, 5, constitutes the landside proper. The inner plate 6 is extended forwardly under the wing of the point, and it carries the later; ally-extending supporting-plate 7, which may be bolted or otherwise securedv thereto and.

which serves to support parts of the plow to be hereinafter described. The plate 6 is'extended rearwardly to the terminal point ot' the plate 5, with which it is connected by means of bolts 8, a washer-plate 9 being ,in terp'osed between the two in order to insure the necessary strength and rigidity of the device. construction the plate 5, which constitutes the landside, may readily be detached and re'-v placed when. desired.

The supporting-plate 7 is provided with' two rowsfor series of perforations designated, respectively, lO and 11,' and upon the top side of said supporting-plate is mounted what I term the adjusting-plate 12, which is pro-y plate is connected with the supporting-plate* by means of tworows or series of bolts designated, respectively, 15 and 16, the lower ones of which, 15, extending through the slots 13 and perforations 10 also serve to secure the wear-plate 17, which is mounted upon the upper side of the adj usting-plate in such a manner as to extend below the lower edge of the latter. the upper slots 14 of the adj usting-plate and through the perforations 11 of the supporting-v plate,also serve to secure in position the moldboard 18, which is so shaped and disposed that its lower edge shall abut squarely against the upper edge ofthe wear-plate 17. The wear-plate 17 and moldboard-l are provided, respectively, with perforations 1Q and 20 to receive the connecting-bolts l5 yand 16.

It will be seen by reference tothe' drawings that while the inner edge of the wear-plate is The bolts 16, which extend throughA Itwill be seen that by this manner of v IOO extended under the wing or flange 2 of the point the corresponding edge of themoldl board is extended above the said iiange,.the upper edge of which forms a shoulder 21, that serves to support the corner of the lower edge of the moldboard.

It will be seen from the foregoing description that the part of myimproved device which I have termed the -adjustingplate is tted or mounted slidingly and adjustably, by reason of the slots formed therein, upon the bolts 15 and 16 and between the supporting-plate 7 on the one side and the moldboard 18 and wear-plate 17 on the other. It will also be observed that the lower edges of the wearplate and the supporting-plate are extended below the lower edge of the adjusting-plate, even when the latter is at its lowest point of adjustment. It will furthermore be observed that the adjusting-plate serves to space the su pporting-plate and the wear-plate from each other. This is to provide for the insertion between the said plates of the lay or share 22, the upper edge of which will abut, as shown, against the lower edge of the adjusting-plate, and the inner edge of which is extended under and protected by the wing or flange 2 of the point. The exact shape of the share will be understood by reference to Fig. 7 of the drawings, from which it will be seen that its upper and lower edges are parallel to each other, while the ends are cut off at corresponding angies, thus permitting said share to be reversed and either side thereof to be exposed to wear. Owing to the peculiar construction and arrangement of parts, asl herein described, I find it unnecessary to use any bolts or other fasteningdevices for securing the share in its operative position, it being held firmly clamped between the lower edges of the supportingplate and the wear-plate, its upper edge being abutied against the lower edge of the adjusting-plate, so as to prevent it from being displaced in an upward direction. The inner edge of said share is furthermore protected against displacement by the wing 2 of the point under which it extends.

By loosening the nuts upon the bolts 15 and 16 the position of the adjusting-plate may be changed so as to raise or lower its lower edge with relation to that of the supporting-plate. It will thus be seen that any desired portion of the share or lay may be exposed to wear; also, that when it has been partly worn the adjusting-plate may be lowered, so as to push or force the share in a forward or outward direction, thus compensating for wear upon the edge thereof.

The supportingplate is provided at its outer lower corner with a depression or indentation 25, forming a bulb or enlargement upon the under side thereof, the said bulb forming an additional support to guide the `plow while cutting the furrow. This method of construction is resorted to because the supporting-plate as well as the remaining parts of my improved device are in practice to be made of much lighter material than that which is usually employed in the construction of plows.

By the construction of the plow as hereinbefore described I am enabled to construct the same of extremelylight material, the heaviest part relatively being that which enters into the construction of the point and landside. These parts, which practically form the base or support of the device, should be made reasonably strong and heavy, the remaining parts-namely, the supportingplate, thc adjusting-plate, the wear-plate, the moldboard and the share-may all be made extremely light, aconstruction which is made possible by the peculiar method of connecting and bracing the parts which have hereinbefore been described and which may be said to constitute the gist of my invention.

While I have in the foregoing described the preferred construction of my improved plow, I would have it understood that I do not wish to be regarded as limiting myself as to the details thereof, but reserve the privilege of making any changes and modifications which may be resorted to without departing from the spirit of my invention.
